SPOOLING MECHANISM.

Original No. 1,545,451, dated July 7, 1925, Serial No.

- filed June 3, 1927.

This'invention relates to a new and improved spooling mechanism of the type generally used in winding wire upon a spool or the like and associated with a wire drawing machine.

There are numerous other uses to which this mechanism can be applied and therefore I do not limit myself to the use aboveset forth.

It is the object of this invention, among other things, to provide a mechanism of the character mentioned wherein the rotary spindle will receive a reciprocatory motion adjustable in length but uniform. in the speed of its travel, and both of these actions controlled by a make and break connection with a source of power, of simple design, that is readily controlled, and to accomplish these and other desirable results withmechanism 01' simple design, that is economically constructed, and readily assembled, so as to withstand the maximum strain, with the minimum wear.

To these, and other ends, my invention consists in the spooling mechanism, having certain details of construction and combinations of parts, as will be hereinafterdescribed and more particularly pointedout in the claims.

Referring to the drawings, in which like numerals of reference designate like parts in the several figures;

Figure 1 is a fragmentary front elevation of my improved spooling machine, partly in section; and

Figure 2 is a fragmentary transverse sectional view thereof, the parts in section be ing taken generally upon line 2-2 of Figure 1.

This type of mechanism is usually associated with a Wire drawing machine for winding on a spool the wire drawn thereon. \Vith some machines the spool moves back and forth while rotating, during which time the wire is wound thereon between the flanges thereof and in other cases the spool may merely rotate without a reciprocatory' movement, in which case the'wire is, guided thereon. e

i In these operations it is desirable that the spool or the guide, whichever it may be,

- should move back and'forth at a uniform speed so as to insure a uniform winding of 714,441, filed May 19, 1924. Application {or reissue Serial No. 186,363.

the wire. This is accomplished in my invention with mechanism that will permit ofsuch adjustments as will vary the extent of the reciprocatory movement Without varying the uniform speed of travel thereof and the exercise of the minimum labor and Referring to the drawings; '10 designates the body of the machine, to the underside of which is fixed the companion brackets 11 within which is slidably mountedthe traverse bar 12 that is held against lateral movement in one direction by the caps 13.

This body member may be otany convenient form or shape and mounted upon standards or legs, or attached directly to a wire drawing or similar machine, or otherwise supported, within the spirit of my invention.

Secured on the top of the body.10 are the standards 14 and 15, within the formerof which the spindle 16 is rotatably mounted and in the latter of which a sleeve 17 is. journaled, being held against endwise movement in one directionby a collar 18 and by a shoulder 65. The spindle is slidable within the sleeve 17 and held against rotation therein by the key 35 which projects into a spline or keyway in the spindle. On one end of the spindle 16 isa spool1 9, which is connectedtherewith in any wellknown manner. The shape, form and size of this spool obviously can be varied, and it may be at tached or secured to the spindle also in any well known or convenient manner.

The sleeve 17 is rotated through a cone pulley 20 which is rotatably mounted upon the sleeve 17 and driven by a belt from any source of power. Slidably mounted upon the sleeve 17 but held against rotation there on by a sliding fit key 22 is a cone pulley 21 having an annular groove 23 therein, into which project the blocks 24 connected Within the lever 25, in a well known manner., This lever is hinged at its lower end b the pintle 27 to the post 26 fixed in the b0 y 10 and is connected at its upper end with the link 28 making a toggle mechanism with link 29; 'l

Between the cone pulleys 20 and 21 is afriction disk 32 and surrounding the sleeve 17 between the outer end of the pulley 21 and the lock nuts 33. threaded thereon'- is a;;.

ill

sleeve 17 and spindle 16.'-

The rotation of the spindle is stopped by moving the lever 31 to the left, that is. to

the position shown by broken lines in I ig-.

ure 1, at which time the hinged connection of the links 28 and 29 will be in asubstantially straight line, also outlined by broken lines, with the link 28 engaging the. stop lug 36 on the lever 25. \Vhen so positioned, the pulley 21 is moved to the right and the spring 34 is compressed, thus removing the friction upon the disk 32 and cone pulley 20.

There is no pressure against the blocks 24 within the groove 23 except when the spindle 1G is at rest, therefore, neither the blocks or the groove into which they project are subjected to anything but the most nominal wear. Thus to put the spindle in motion it is only necessary to shift the handle 31. from the dotted to the full line position, which moves the pulley 21 against the friction disk 32, and the compression spring 34 holds it thereagainst with all the pressure that. is-

rcquired to operate the spindle and still per-- mit a slipping of the spool during the winding operation.

It is almost impossible to time the speed of rotation of the spindle 16 with the speed of the wire as it comesfrom the wire drawing machine, and therefore, it is the. practice to rotate the spool at a slightly higher speed and arrange for a relative slip between some.

of the parts. This has'usually been done by a loose belt drive, which is unsatisfactory because among other things it slips at the wrong time, and not sufficiently at the right time.

' The mechanism herein shown [or driving this spindle may be adapted for purposes other than this particular type of machine and the spindle may also be driven by other types of mechanism, for illustration, the

geared mechanism as used on the ordinary engine lathe for driving the spindle.

Journaled in the body 10 and held against endwise movement therein by any convenient form of mechanism, is a shaft 37 having a worm 38 thereon, which meshes into the teeth ofa worm gear 39 fixed on a shaft 40 journaledin a. bracket 41 secured to the body 10 and having a heart shaped cam 42 upon the opposite end thereof.

A cone pulley 43 keyed or otherwise fixed on the shaft 37 is driven by a belt 11 from the cone pulley'21 so that the spindle l6 and shaft 37 come to a full stop at one and the'same time.

Rotatably mounted upon the studs 45 fixed the bar 12 are the cam rolls 46, both of which are always in contact with the face of the heart shaped cam 42. As both sides of this cam are alike, any two points 'diasite ends with slots 48, within the upper of which is 'slidab'ly mounted the block 49 and in.the lower the block50. The block 49 The block 50 is mounted upon a stud 55- that projects through the bar ]2 and having a nut to upon the outer end thereof.

This link bar 47 is pivotally mounted at a pointbetween theends thereof upon a stud 57 having a T-head 58, which is movably mounted within a slot 59 in the body ]O,and is provided with suitable collars 60 and-61, as is usual.

The axis of the shaft 40 is normal to the path of movement of the traversebar 12, which latter is parallel with the spindle 16 sothat a reciprocatory movement of the bar 12 is imparted to thespindle 16. The length of the reeiprocatory movement of the spindle 1.6 is varied within its'extreme limits by shifting the position of the stud 57 that forms a fulcrum for the bar 47, thus producing inthe spindle an absolutely variable length of stroke without affecting its uniform speed of movement. 4

To facilitate adjustment within predetermined limits one t'ace of the body 10 adjacent to the slot 59 is graduated, as at ($2, and a finger (i3 is attached to the link bar 47 and registers with such graduation. I

lVhen this mechanism is designed for use with the type of machine wherein the spool may rotate without a 'reciprocatory movement the sleeve 17 may be entirely omitted or remain integral with the shaft, as desired. r

A guidefinger, or other similar mechanism well known in the art may be substituted for the spool 19.

There are minor changes and alterations that may he made within my invention, aside from those herein suggested, and I would therefore have it understood that I do not limit myself to the exact construction herein shown and described but claim all that falls fairlv with the spirit and scope of the appended claims.
